need help... DDR2 800MHz to @1066MHz?

Reaper X! Starts at 4-4-3-15, OCs 1080 and higher at 5-5-5-15-18. If a google search doesnt do it for you, I can fire mine up and test them to make sure. I have 4x2 GB ones.

You want a pair of those if you wanna use 32 bit winblows, and 4 of em if you have 64 bit!

Yee haw!

i buy 4x2GB, and i use 64bit vista
if i buy OCZ ReaperX HPC
then i need extra 80$

i don't need more 80$ to same clocked /800MHz/ memory.

Fist of all you can't compare most DDR2 2x2 sticks with DDR2 2x1 sticks.

The ICs (actual chips under the heat spreaders) are usaully different chips.

Heres a list of most of the kits available and what ICs are used in producing them - > http://ramlist.ath.cx/ddr2/

I'm sure that the sticks the OP is wanting are Powerchips which offer pretty low latency usually at the expense of poor subtimings (in my experience). They also don't respond to voltage very well which means they also don't have much in the way of overclocking headroom.

Unless you absolutely positively need 4gb of ram there are far better options in 2gb kits. On the list I posted the kits showing "GREEN" ICs are considered the best. They are the actual chips inside the memory; manufactured by a company named Micron and they do not offer any chips for DDR2 that would give you 4gb sticks, only 2gb sticks.

My suggestion is to find a 2gb kit on that list using Micron D9 chips that fits your budget. Though I will say most of them are becomming harder to find as the actual chip makers are starting to focus more on DDR3.

If you want to see a prime example of Micron chips vs. Powerchips and the price they command I present you the Mushkin redline.

$119 mushkin REDLINE 4GB(2 x 2GB) DDR2 1000 (PC2 8000) - POWERCHIPS

$209 mushkin REDLINE 2GB(2 x 1GB) DDR2 1000 (PC2 8000) - MICRON


They are the same series and you'd think they have the same chips inside, but they don't. In fact you pay nearly twice as much for half the amount of ram.

The Micron ICs are true quality overclocking chips and you pay for them. The powerchips are cheaper,offer decent price/performance but they will NEVER be as fast as the Micron chips.

I am confused! Get the cheap junk then!

Enjoy!

thanks.

but... Price per Performance?

$119 4GB(2 x 2GB) DDR2 1000 - POWERCHIPS
$209 2GB(2 x 1GB) DDR2 1000 - MICRON

micron chip cost too high!!! really need it

Theres the new Crucial Ballistix 2x2 sticks.

Crucial is the consumer version of Micron (owned by Micron).
My guess is that they would have Micron chips or overclock very well as some reviews show.

Yes Crucial is owned by micron, but that doesn't guarantee that they get all the high bin chips from Micron. In fact the lattest batches of ram from Crucial have reportedly been very poor performing ICs (speaking of the 2x1 kits). Also to Silverion7 7, the Crucial Ballistix 2x2 sticks still won't use Micron chips. Micron does not make DDR2 in that size period. My guess is that it's the same Powerchips that everyone else is using in their 2x2 DDR2 kits.

I finally just bit the bullet and decided to go with DDR3 for scalability since DDR2 is pretty much at the end of it's life cycle and truely doesn't hold much in the way of future gains. Price difference between high end DDR2 and DDR3 isn't really an issue either. Budget DDR3 will be out at some point I'm sure though.

munkh, why do you need RAM faster than DDR2-800 speed? DDR2-800 is plenty for up to 1600MHz FSB datarate.

i planned
Q9300 @ 4.0GHz = 7.5*533

1:1 (FSB:MEM)

then i need 1066MHz DDR2 Memory

You will not be able to get 533 FSB out of a quad. Period.

Even the best overclocking boards available hit a wall around 450-460 on quad core chips which is why most enthusiasts think the Q9300 and Q9450 chips are inferior (ie. very overpriced) compared to the Q6600 with it's 9x multiplier. You can hit 500+ FSB with core 2 duos like the e6700 or e8400; not quad core chips. Do a little more research on the subject imo.



Btw newegg has a great price on TWIN2X2048-6400C3DF for $109 after MIR. Killer deal for the some of the fastest hand picked DDR2 available. You'd have to loosen up the timings for anything over 400fsb, but this kit is well worth the price of admission. Lifetime warranty and 2.4v maximum though I'm not sure how long the ICs used that particular kit will even be available.
